Whenever im talking to people online using my microphone they can hear whats happening in my headset speakers (eg. Playing music while on teamspeak/ventrillo or when im playing counter-strike and talking).
This is what my master volume looks like; the advanced options microphone boost is unticked. http://img151.imageshack.us/my.php?image=picdi0.png
